装备项目型供应链风险控制策略

项目型供应链管理模式能有效实现装备研制过程中行为主体间的优势互补和资源的优化配置,利于供应链整体效益的提高,但各种不确定性因素会导致主体间风险传递行为的发生。为提供风险控制有效对策,通过考虑节点位置重要度和属性重要度,构建了项目型供应链节点重要度评估模型;通过衡量行为主体风险识别和风险控制的努力程度,给出了行为主体抗风险努力程度的评价方法,最后提出了一种基于节点重要度和抗风险努力程度的项目型供应链利益分配策略,该策略能有效促使行为主体主动进行风险识别和风险控制,是一种"风险共担、利益共享"的项目型供应链合作博弈策略。     

Making long-range planning work: the case of the US Army's 30-year strategic modernization plan

The extensive timespan of evolving assumptions about future adversaries, US military engagements, and technology inherent in the US Army's 30-year modernization strategy can overwhelm the management capacity of planners, and misdirect acquisition investments. Some military scholars have argued that long-range planning is futile due to the complexities of the global security environment. So how can the US Army manage the evolving assumptions inherent in its 30-year modernization strategy to ensure it remains a superior global force? This study will answer the above question by arguing that the US Army's 30-year modernization strategy, while emulative of a similar modernization approach in the threat-based planning environment of the Cold War, is viable if supported by a method and a tool that manage investments and planning assumptions.     

应急器材柔性采购定价建模与求解

由于当前应急器材储备依然存在“多储”或“少储”风险,为提高储备效益,以企业经济效益与军队采购成本为优化目标,提出了应急器材柔性采购策略。通过建立企业储备策略与军队采购定价最优化模型,求解得到了在不同战争爆发概率及器材现货市场价格区间等外部环境因素下的军队最佳柔性定价及对应的企业最优储备策略,并通过实例分析验证了得出的决策结论。结果表明,最优策略的实施将有利于军队与企业共担应急器材数量储备风险。     

复合假设下导弹可靠性指标Bayes检验方法

在用Bayes方法对海防战术导弹可靠性指标进行假设检验时,原假设和对立假设均采用简单假设的形式,而此种方法可能导致使用方Bayes风险增大。从理论上阐述了简单假设Bayes检验方法可能导致使用方Bayes风险增大的原因,同时给出了用于取代简单假设的复合假设Bayes检验方法,并用实例证明了它比简单假设Bayes检验方法科学、合理。     

边境安全风险评估矩阵模型构建研究

提出边境安全风险和边境安全风险评估的概念。围绕边境安全风险状态和边境安全风险类型两个维度构建边境安全风险评估的矩阵模型。其中,边境安全风险状态维度包括边境安全风险源活跃度、边境安全风险源聚集度、边境安全风险供应链成熟度、边境安全风险源异常度;边境安全风险类型包括外生型边境安全风险、内生型边境安全风险、网络型边境安全风险、跨境型边境安全风险。并论述了边境安全风险评估矩阵模型的应用。     

边检执勤执法风险评估制度的实践反思及理论建构

边检执勤执法风险评估是理论研究缺失下的制度实践,为避免出现“形式化”、“走过场”的弊病,亟须对其进行系统反思,并对风险评估制度的基本范畴、合理根基、合法来源、体系构成及目前实践中存在的问题以及改进的空间进行研究,在理论上构建并完善边检执勤执法风险评估制度,以进一步指导和完善边检机关风险评估工作实践。     

棕垫材料火灾危险性的热解动力学研究

利用热重分析仪,通过空气与氮气下棕垫材料的对比试验,建立热解表观动力学模型,对棕垫材料的火灾危险性进行分析。通过对试验数据的分析表明,在空气气氛下,棕垫材料第一步失重阶段热解表观动力学模型较好地符合相界反应球形对称模型,第二步与第三步失重阶段较好地符合二级反应模型,活化能范围为32.42-59.09 kJ·mol^-1;在氮气气氛下,棕垫第一步失重阶段较好地符合二级反应模型,第二步失重阶段较好地符合零级反应模型,活化能范围为56.92-72.56 kJ·mol^-1。对比分析其他室内材料的燃烧属性表明,棕垫材料活化能较低、热稳定性差。说明棕垫材料是一种易燃烧物质,火灾危险性较大。     

Unemployed youth: ‘time bombs’ or engines for growth?

While popular narratives about success in South Africa focus on individual effort, accidents of birth continue to determine life prospects. Inequalities in early childhood development, health, and education narrow the range of possibilities that young people have available to them, and this impacts on their risk appetite, including, through the workings of the maturing brain, a propensity to violence, substance abuse, and unsafe sex. New technology offers young people an unprecedented ability to organise and network. This fact, combined with high levels of youth dissatisfaction, unemployment, and marginalisation, leads many to worry that the young are “ticking time bombs”. While there certainly are risks, great unused pools of youth labour also present an opportunity for engaging them in social advancement programmes. Structured youth service is a tried and tested policy option that, when implemented as part of an integrated youth development strategy, can enlist thousands of young people in devoting their considerable energies to leadership for the public good.
